it's not so much to prevent someone stealing the device, it's more to protect whatever info you keep on it like bank details, pin numbers etc (not that you ever should keep that on the phone)

also, it will most likely give email access without a password in which you might have scans of passports, driving licenses etc. Not me, but maybe you like to keep racy photos of yourself or anyone else you know, would you want that out there in the public?!

could be anything, hence, if you have any of that sort of info on your phone, it should always be protected with a pin or swipe or your face (on certain phones).

I don't bother, it doesn't stop people resetting your phone via recovery if it gets stolen and I don't leave it lying around for people to go snooping through. Also, I can't be bothered to type in a code every one of the hundreds of times a day I check my phone.
